From 003cb608a2533d0927a83bc4e07e46d7a622eda9 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 2 Feb 2010 14:39:01 +0900 Subject: percpu: add __percpu sparse annotations to fs Add __percpu sparse annotations to fs. These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds.
